Abstract
The invention relates to a research on a method for alloying the casting surface of a medium manganese steel; in order to effectively solves the defect that the abrasion resistance of the medium manganese steel is bad in initial use, the invention provides a technology which can control the manganese content in the medium manganese steel, the melting process and regulate the casting penetration agent and the casting penetration process; the invention promotes the initial abrasion resistance of the medium manganese steel cast by controlling relevant alloy components, melting temperature, casting penetration agent components and casting penetration process.
Description
Affiliated technical field:
The present invention relates to a kind of cast member surface-alloying process, especially Medium Manganese Steel casting surface alloying processing method.
Background technology:
The initial hardness of Medium Manganese Steel foundry goods is lower, in order to improve the wear resistance of parts locally, people adopt diverse ways to make surface alloying, particularly hard carbide such as WC, TiC, SiC are made composite bed at piece surface, can improve the surface abrasion resistance of material significantly.But for mines such as ball grinding machine lining board, bar, the metallurgical part that uses, process for surface coating complexity when adopting thermo-chemical treatment, need longly with the time, infiltration layer is more shallow, cost height and can not using.The Soviet Union had once used the casting surface alloying process on the high mangaenese steel bucket tooth, but infiltration layer is more shallow, and surface hardness reaches HV477-514, and domestic centering austenitic manganese steel casting surface-alloying process does not appear in the newspapers so far.This experiment uses RE as catalyzer first, adopt casting to ooze technology, form hardness on the foundry goods top layer and reach the wear-resistant composite bed of 6mm up to HV700, depth of penetration, improve the surface hardness of Medium Manganese Steel foundry goods, can obtain thicker infiltration layer and high wear resistance at short notice, save energy is used the problem that wears no resistance at initial stage thereby solved Austenitic manganese steel casting.
Summary of the invention:
In order effectively to improve the shortcoming that Medium Manganese Steel uses the initial wear-resisting performance difference, the invention provides manganese component content in a kind of control Medium Manganese Steel, melting technology and allotment casting penetration enhancer and casting and ooze technology, this invention is to reach the purpose that improves the initial wear resistance of Medium Manganese Steel foundry goods at control associated alloys composition, smelting temperature, casting penetration enhancer composition and infiltration casting technique.
Technical scheme:
Reach 7～9% preparation Medium Manganese Steel compositions by manganese content, adopt medium-frequency induction furnace fusing molten steel, carry out melting, casting, add the steel scrap and the pig iron earlier, all fusing back adding manganese content reaches 7～9% ferromanganese, after this add and be equipped with good lime, fluorite, the aluminium powder compound, make the thin slag of reduction, treat to insert aluminium deoxidation behind its reacting balance, in the time of tapping temperature 1550-1600 ℃, be granularity 100 purpose ferrochrome powder earlier, 6.0% resin, 5% yellow soda ash, 0.2% rare earth stirs in container, add dehydrated alcohol then, the casting penetration enhancer brushing of the pasty state that modulates on sand mold mould wall surface, is lighted oven dry, when the molten metal temperature is 1480-1530 ℃, pour in the casting mold of brushing the casting penetration enhancer, treat the foundry goods cooling, can obtain the foundry goods of top layer high abrasion behind the knockout.
Beneficial effect:
Beneficial effect of the present invention is that the middle Mn austenitic steel casting surface alloying process of being developed is widely used in mines such as ball grinding machine lining board, bar, the metallurgical part that uses.The casting diffusion agent formulation is reasonable,, forms surface hardness and reaches the complex abrasion-proof layer of 6mm deeply up to HV700, infiltration layer as catalyzer with RE, improves the partial wear resistance of foundry goods, solves the low shortcoming of Medium Manganese Steel cast(ing) surface initial hardness, satisfies service requirements.
Embodiment one:
Reach composition in 7～9% preparation Medium Manganese Steel by manganese content, adopt medium-frequency induction furnace fusing molten steel, carry out melting, casting, add the steel scrap and the pig iron earlier, all fusing back adding manganese content reaches 7～9% ferromanganese, after this adds to be equipped with good lime, fluorite, aluminium powder compound, makes reduction and approaches slag, treat to insert aluminium deoxidation behind its reacting balance tapping temperature 1550-1600 ℃.
Embodiment two:
Is granularity that 100 purpose ferrochrome powder, 6.0% resin, 5% yellow soda ash, 0.2% rare earth stir in container, adds dehydrated alcohol then, and the casting penetration enhancer brushing of the pasty state that modulates on sand mold mould wall surface, is lighted oven dry.When the molten metal temperature is 1480-1530 ℃, pour in the casting mold of brushing the casting penetration enhancer, treat can obtain behind foundry goods cooling, the knockout foundry goods of top layer high abrasion.
